Feature request: detect '#!' lines

[JRobert]

Terrific tool - thank you. I use it to compare unix scripts in various languages, but with suffix-less file names. It would be really useful if DiffMerge could (optionally) look for and use the shebang line:

Code: Select all

#! <path_to_interpreter>

as another way to decide which ruleset to use, in the absence of a suffix.
Also, since I run DiffMerge with a wrapper script, if there were a way pass a suffix string (eg. "-e=.awk") on the DiffMerge command line, the wrapper could select the ruleset for suffix-less files.

Two excellent suggestions. I've been wanting to do the --suffix=".awk" for a while now.
I hadn't thought about the #! trick. I'll log both of these.

In the mean time, you can modify the "default" ruleset (which is only used when
there is no matching ruleset) to do what you want. I know it's not optimal since
it would treat a variety of different script languages the same, but it may be
helpful....

I've just upgraded DiffMerge for the first time since this conversation from 5 years ago (that speaks well for how solid your code is!)

Has this suggestion - to detect shebangs - ever gone any further? I don't find any references to 'shebang' or '#! in the manual.

This hasn't been coded yet. I've added a note so that the developers are aware that there still is interest in this item.
